Elastic buckling of plates containing eccentrically located circular holes
Abstract The finite elements method is used to obtain the elastic buckling loads for flat square panels containing eccentrically located circular holes. The applied inplane loads considered are uniaxial and biaxial compressions as well as pure shear. In all cases the load is distributed uniformly along the simply supported or clamped outer edges. The effect of the degree of eccentricity and the size of the hole on the buckling load is obtained. The triangular and rectangular finite elements used for calculating the inplane stresses prior to buckling are based on assumed strain, rather than displacement, fields and satisfy the exact representation of strain free rigid body modes of displacements. The combination of these elements with existing well-known bending elements is shown to produce results of acceptable accuracy without the use of an inordinately large number of elements.
